In recent years, there has been a surge in research on autonomous mobility. The evolution of services, including mobility, has advanced to the point where designing optimal spaces for humans in architecture does not necessarily equate to creating spaces that are optimal for humans anymore. Therefore, this design presents a new societal concept that integrates autonomous mobility with architecture. It aims to foster social interaction and coexistence by aligning the advancement of mobility with architectural design, contributing to the creation of universal design where diverse entities coexist. The proposal suggests four types of mobility that invigorate local commerce and encourage social interaction, along with architectural designs that adapt to these mobilities. In a society facing population decline and aging, the collaborative relationship between mobility and architecture is explored as a key to reinvigorating social interaction.
